Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Egg yolks
Thicken the dressing and add richness as they set gently with the warm mixture.
Milk
Forms the liquid base that thickens with the heat and yolks.
Vinegar
Adds acidity that gives the dressing its tangy flavour.
Sugar
Balances the acidity of the vinegar with a touch of sweetness.
Butter
Adds fat for a smoother, richer mouthfeel.

The step that matters

Cook the mixture gently while stirring constantly. Milk and egg yolks can curdle or scramble if the heat is too high or stirring stops. Constant stirring over medium heat lets the mixture thicken evenly into a smooth, creamy dressing.
